DP-300 Implement a secure environment Practice Question
Your company uses Azure SQL Database. You need to ensure that all connections to the database use TLS 1.2 or higher. Currently, some client applications are connecting using TLS 1.0. What should you do?
⚠ Common exam trap
Many candidates think updating client applications (Option D) is sufficient, but the exam tests the understanding that server-side enforcement is required to guarantee compliance across all clients, especially when you cannot control or update every client application.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the 'Minimum TLS version' property of the logical server to 1.2.
Setting the 'Minimum TLS version' property of the Azure SQL logical server to 1.2 enforces that all incoming connections must use TLS 1.2 or higher. This server-level setting overrides any client-side configuration, blocking connections that attempt to use TLS 1.0 or 1.1. It is the simplest and most effective way to enforce the minimum TLS version across all client applications without requiring changes to each client.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure the server firewall to block non-TLS traffic.
Why it's wrong here
Incorrect: Firewall rules do not enforce TLS version.
- ✓
Set the 'Minimum TLS version' property of the logical server to 1.2.
Why this is correct
Correct: This enforces TLS 1.2 for all connections.
- ✗
Set the 'tls_version' database parameter to 1.2 in the master database.
Why it's wrong here
Incorrect: TLS version is set at the server level, not via database parameters.
- ✗
Update the client applications to only use TLS 1.2.
Why it's wrong here
Incorrect: This is a client-side fix, not server-side enforcement.
